This Sunday, Oct. 7, SpaceX is scheduled to launch their Dragon spacecraft carrying important supplies and equipment to the International Space Station. You can get an inside scoop on the launch right here, in this Google+ hangout between SpaceX CEO Elon Musk and NASA administrator Charles Bolden, starting at 10 a.m. Pacific/1 p.m. Eastern.

This will be the second flight of the Dragon spacecraft to the International Space Station, following a historic rendezvous in May. SpaceX is under contract to provide a resupply ship for U.S. astronauts and equipment to the ISS so that NASA can focus on other missions to asteroids and beyond. This launch is the first of 12 planned flights for the Dragon, which will be filled with 1,000 pounds of supplies and will return 734 pounds of scientific material on its way back to Earth.
